This study is an attempt to investigate the effect of welding rotational and traverse speed on mechanical and microstructural properties of A 430 stainless steel in order to give an effective processing window to achieve an appropriate microstructure and so mechanical properties. There are a wide range industrial uses for ferritic stainless steel. There from they have some problems like grain c...
in the present work, the influence of aging temperature on mechanical properties and sound velocity of maraging steel m350 was investigated. for this purpose, first, samples were solution annealed at 825◦c for 2 hours and then age hardened at 510◦c-600◦c for 3 hours. hardness, tensile and impact tests were used for determining mechanical properties and longitudinal ultrasonic velocity was used ...
In this study, nanoparticle zinc ferrites with different particle sizes were synthesized via sol-gel method using ferric nitrate and zinc nitrate. The obtained gel was dried and calcined at three different temperatures (i.e. 500, 600 and 800 °C) for 2 h. Adequate amounts of the as-synthesized nanoparticle samples were then added to the mixture of polyester resin and formaldehyde resin. The ...
In the present work, a high power Nd:YAG laser has been employed to weld AISI 430 ferritic stainless steel thin sheets. Optical microscopy was used to study the microstructural evolutions during laser welding. Tensile test and microhardness measurement were employed in order to investigate the mechanical behaviors of welds. Also, vibrational sample magnetometry was used for characterizing magne...
Aluminum foam has received considerable attention in various fields and is expected to be used as an engineering material owing to its high energy absorption properties and light weight. To improve the mechanical properties of aluminum foam, combining it with dense tubes, such as aluminum foam-filled tubes, was considered necessary. In this study, an aluminum foam-filled steel tube, which consi...
this paper investigated the effects of combining fibers with self-consolidating concrete (scc). 12 series of test specimens were prepared using three kinds of fibers including steel, polyphenylene sulfide (pps) and glass fibers with four different volumes fractions and one specimen without fibers as a reference sample. all plans were subjected to fresh concrete tests. for mechanical behavior of...
